Summary: x86_64 JIT compiler optimizations
Product: ioquake3
Version: SVN HEAD
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P3
Component: Platform

The x86_64 qvm JIT compiler is very slow, often taking around 5 seconds to
compile a qvm. This patch caches compiled vms so that a recompile is not
necessary when the same qvm is reloaded. I also disabled a debug #ifdef which
causes unnecessary instructions to be emitted.
